' PATCH FOR PNEUMATIC TIRES.

Specification of Letters Patent.

Patented Feb. 6, 1912.

Application filed March 9, 1911. Serial No. 613,219.

' To all whom it may concern Be it known that I, CLARKE IV. McKnn, a

citizen of the United States, and a resident of San Diego, in the countyof San Diego .and State of California, have invented certain new and'useful Improvements in Patches for Pneumatic Tires, of which thefollowing is a specification.

My invention relates to patches for pneumatic tires and is moreparticularly adapted to be used in cases ofblow-outs or ruptures in theouter casing which allows the inner tube, which is of soft rubber, to bealso ruptured, thus rendering the tire useless.

The objects of my invention are to provide a simple and economical meansfor pro- I tecting the inner tubes at the places of puncture or rupture,thus enabling the user to proceed without the necessity of immediatelytaking the casing to a repair shop.

With these and other objects'in view as will appear, my inventionconsists of certain novel features of construction, combination andarrangement of parts as are hereinafter described in detail and moreparticularly set ,forth in the appended claim, reference being 'had tothe accompanying drawings and to the characters of reference thereon,which form a part of this specification, in which- Figure 1 is atransverse section of an outer casing, inner tube and wheel rim showingmy device in connection therewith, Fig. 2 is a perspective view of thedevice, and Fig. 3 is a side elevational view of a portion of aninflatedinner tube and showing my de vice inoperative connection therewith.

Similar characters of reference refer to similar parts throughout theseveral views. My device consists of a piece of pliable material whichis as near non-elastic as pos-- sible, and tapers gradually on each sidefrom pointl to the end 2. From point 1 the material is extended to point3, then folded back against itself to point 1 again, then extended topoint 4 and folded back against itself to point 1 again. These two foldsor flaps are substantially sewed together, and along the outer edgesthereof is aplurality of holes 5 adapted for lacing. The fold or flapextending to'point 3 is short, being only long enough to provide for theholes 5, while i around the inner tubing several times, be

ginning with the end 2. The material being tapered causes each layer ,tooverlap the prior one. It is made of a sufficient length to wrap aroundthe tubing several times and then the two flaps are placed over theportion wrapped, and laced together by means oflacing 6 as shown best inFig.3.

In the drawings 7 represents the inner tube, 8 my patch, 9 the outer therim.

It is obvious that I have provided a patch fonpneumatic tires which maybe economically and easily applied and that bythe wrapping of thematerial several times around the tubing and the material being asnon-elastic as possible, and thoroughly laced around the inner tube atthe place where the rupture is, there will be provided a good andsubstantial patch which may be used temporarily, or in case the outercasing is not too badly injured, may be used for a considerable time,thus adding to the life of the tire.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is A patch for pneumatic tires comprising aband of practically non-elastic material tapered toward the one end, theother end thereof beingprovided with a short flap adapted for lacing andanother longer flap similarly adapted andof sufiicient 'length when usedin connection with said short flap to reach around the inner inflatedtube, and means for lacing the two edges of the said flaps together, allsubstantially as set forth.

In testimony whereof, I have hereunto subscribed my name in the presenceof two subscribing witnesses.
